I enjoyed my stay at Terachai's place. The location worked well for me as the place is near the Westin Grand (1 min walk) and I could schedule all of my organized tour pick ups from the Westin Grand lobby.
Terachai is extremely helpful and kind. He sent me lots of helpful info. on sightseeing and was always responding within a few minutes if I needed anything. My bed was super comfy and I slept great. The AC works well. I was able to do laundry and the housekeeper is really kind. There is a mall right next door, Terminal 1, which has lots of eating options. There are massage places in front of the building too so that was great. I would love to stay here again!
